How can I effectively store garden tools in sand to prevent rust and maintain their sharpness?

To effectively store garden tools in sand to prevent rust and maintain their sharpness, clean the tools thoroughly to remove any dirt or debris, then coat them with a light layer of oil to prevent rust. Next, bury the tools in a container filled with sand, making sure they are completely covered. The sand will help absorb moisture and keep the tools dry, preventing rust. Check the tools periodically for any signs of rust or dullness, and reapply oil as needed.
